proved Filler-Machine, of which the followlnga full, clear, and exact description.

This invention relates to a machine for making fillers for packing cases such as e g boxes. These llers are formed of strips d1s.

posed in parallel rows and extending transversely 0 each other so as to form separate compartments for the individual articles packed in 4thfpacking case.,

The object of the mvention is to produce a-machine which will operate automatically to form these `stri s in such a way that they can interlock witl each other, and further providesmeans for bringing the strips into position so that they will lock together and formthe filler.

The invention consists in the construction and combination of parts t0 be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings formin a part of this specification,in which lsimi ar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a machine constructed according to my invention; Fig.

2 is a planof the machine; Fig. 3 is a front elevation "df the machine; `Fi 44 isa rear elevation; Fig. 5 is 'a'vertica longitudinal section through the forward part 4or front of the. machine, the rear portion of the ma.- chine being broken away; Fig. 6 is a verticalv section through the rear portion of the machine, certain parts being broken away; Fig. 7 is a longitudinal vertical section, certain parts being broken away, through a finger druml which yconstitutes a feature of the invention; the function of this drumbeingto insert the transverse strips in the longitudinals; Fig. 8 is an elevationof the drumshown in Fig. 7, viewed from the right side, parts being in section on the line 8-8 of Fig. 7

Fig. 9 is an elevation showin Athe knife which cuts -oflt' the fillers when t ey are finished, this View showing also, the. means for controlling the operation of the knife; Fig. 10 further illustrates the knife, and is a horizontal section taken on the line 10--10 of Fig. 9; Fig. 11 is a plan of the die which is employed in punching the main strips or longitudinale of the filler; 12 is al similar view, showing the dies which are employed in punching the transverse strips of the fillers; Fig. 13 is' a plan of the guide which guides the longitudinal strips into position to receive the transverse strips or one Aof t e longitudinal strips cut oi in proper length; 1n the operation of the machine, these strips are fed through in the position shown in this igure, and the trans" -verse strips are brought into osition beneath them, for this reason, I s all refer to these strips hereinafter not only as longitudinal strips, but I shall call them .overstrips; Fig. 15 illustrates one of the transverse strips'which are fed upwardly by the finger drum so as to engage with the overstrips to form the complete llers- I shall refer to these strips shown in this figure, as under-strips hereinafter, for the reason that they come into position fromthe under side; Fig. 16 is a side elevation showing, in detail part of the means for transmitting the feed movement to the longitudinals orover-strips as they ass through the machine; this view especial y illustrates a construction by means of 4which the operation of the punchers and dies is modified at the ends' of the overstrips Fig. 17 is a cross section taken at one end o the linger drum, and showing a small portion of the drum, illustrating the construction and mode of operation of certainfingers carried b the drum which feed the un er-strips Ito t e over-strips; and Fig. 18 is a plan of a complete' filler.

Referring more articularly to the parts, and e'speciall to igs. 1 to 4, 1 represents 'the frame o the machine, which has the generalform shown. In the forward part of the frame in an elevated position, a main shaft 2 is rotatablysu ported. As indicated in Fig. 3, this sha ably at 'the left of the mac ine, and is provided with-a belt pulle 3 by means of which the machine is griven as will be a pinion 4 is ,provided on the main shaft 2, and this pinion operates to drive a main gear Wheel 5 which is carried upon the extended Ashaft 6 of a roll 8. vThis roll 8 is mounted in a transverse position, and is disposed directly below a similar roll 7. The details of this arrangement are most clearly shown in Fig. 5. As indicated, however, 1n Figs.

2 and 3, these rolls 7 and S are provided with cross stri s of the llers;Fig. 14 illustratesprojects consider- I 4 readily understood. Near the belt pulley 3 circumferentially disposed knives or cutters 9 which are disposed an equal distance apart and opposite to each other, so that when a strip or band of paper stock is fed between the roll's these rolls operate to cut the same longitudinally into strips. These strips form "the longitudinals or over-strips referred to above.

Above'the die bar 13 upwardly projecting guide stems 15 are provided, and on these stems 15 a punch bar 16 is'guided up and down. The arrangement for reciprocating this punch bar will be described more' fully hereinafter. The under side of the bar is provided with a punch or punch plate 17 which iits the die plate 14, as willbe readily understood. On the rock shaft 12 a rigid -arm 18 is provided, which extends Vup- 'wardly :as-indicated in Fig. 5, and it is through the medium ofy this arm that the rocking frame 11 is moved to and fro during the operation of the machine.

' Referring now especially to Figs. 1 and 6, near the middle of the machine on the upper side of the frame, a bracket 19 vis provided, andv in this bracket feed rolls 20 and 20a are mounted, as indicated. The roll 20 is 'rigidly attached to a shaft 21, which shaft projectsat the left of the machine, and car.

ries Va rigid sprocket wheel 22. Over this stood that'the stock whih is to form the under-strips passes between the rolls 2O and sprocket wheel a sprocket chain 23 runs, and this sprocket chain is driven continuously during the operation of the machine from the sprocket vwheel 24 which .is rigidly mounted on the main shaft*2 as indicated most clearly in Fig. 3. It should be under- 205. VJ ust beyond these feed rolls 20 and 20a a rocking'frame or punch frame 25 1s provided, which is similar in 'construction' to the punch or .rocking frame 11 described above.` The lowerendpf the frame is pivotally mounted by ,-.meansof a rock shaft-26 whichis supported .-on a cross .bar 27, inthe lower part of the frame;v The 'upper part 0f this punch frame just vto the rear of the'.

rolls and-on the same level therewith, is

provided with -a horizontal diel bar 2.8carrying a dievplate 29. The* form of this die' plate is clearly'shown in Fig. 12. The diebar 28 isprovided with upwardly extending guide stems 30 on which there is guided a' punch bar 31.-` The under side of this punch.

esono I har 31 is rovided with a punch or punch plate 32 w ich fits thev die plate 29. -As indicated in Fig. 4, the rock shaft 26 is provided. with an upwardly extending rigid arm 33,- which is similar to the corresponding arm 18 on-the rock shaft l2. ,I provide means for rocking these two punch'frames simultaneously. For this purpose, Vabout midway 4between thenn'as indicated in Figs.

1 and 2, I provide a cross bary 34 which is 75 attached in the upper part of the frame, as indicated. Near its middle oint, cross bar .is provided with a racket 35; which supports a vertical rocking `pin 36.

This rocking pin is' provided with a rigidgg.

arm 37 which. extends toward the left of the machine, and this arm 37 is connected by a horizontal link 38 with the upper' end ofthe aforesaid arm 18. This arrangement is shown very'clearly in Fig. 5'. Near the 85 lower part of the rocking pin an arm 39 extends oppositely to the arm 37 This arm 4is also rigid with the rocking pin, and` is vconnected by a link- 40 with the upper end of the laforesaid arm 33. 'I provide means 90 for vrocking the rocking pin so vas to move the arms 37 and39. .For this purpose, near its lower end, as indicated in Fig. 5, the rocking pin is provided witha cam arm 41 which extends forwardly and is providede's-4 at its forward end with an upwardly projecting conical roller 42. -This roller is in engagement'with a helical cam 43 which is rigidly attached to the main shaft 2. From.

an inspection of Fig. 2, it will be evident that as the cam 43 rotates, the arm-41 will be rocked from side to side.- In this way a reciprocating'movement is. imparted to the' links 38 and 40. I provide means, also, for

reciprocating the punch bars 16 and 31)'105 For this purpose, in the lower part of the frame, as indicated in Fig. 5, there is lprovideda rock shaft 44 upon which there are mounted two rockersorjacks 45. These jacks have the form of crab-shaped frames,

and the upper ends of the frames are provided with pins 46 to which the ends of eccentric rods 47 areattached.. These eccentric rods 47 y extend outwardly fromV eccentric straps 48 which are receivedon eccen- 115 tricl sheaves 49 which are rigid with the main shaft 2. From this arrangement, it will be evident that as the shaft rotates, the jacks or rockers l45 will rock on the shaft 44.

The forward ends of the jacks 45 are con- 120 nected yby pivot pinsv 50 to upwardly eX- tending links 51, as indicated in Fig. 3, and these links at their upper ends, areV pivotall attached to theends ofthe` punch barl In-this way, as the forward ends of the jacks jmove down,r the`punch bar 16 slidesdown- -wardly on the guide stems 15 so as to punch the stock as it .passes toward the rolls 7 and 8. In a similar manner., las indicated in 1 and 4, the rear ends of the jacks are 133 this mounted at 67 on the side of the plate 'the under-strips as vit comes Vfrom the rolls 20and 20.

Referring especially to Fig. 6, I provide means for cutting the stock which is unched by the punches 32, into strips. or this purpose, the rear face of the punch bar 31 'is provided witlia knife 54 which coperates with a similar knife 55 which is fixed to thel corresponding face of the die bar 28. The knife 54 is formed with a beveled ed on its outer side. On the'outer side of t ie die bar 28 there is provided a plate 57 which is pivotally mounted at 58 and normally held pressed against 'the outer side of the knife 55 by means of a spring 59. As the knife 54 descends, its beve ed edge 56 strikesV the u per edge of the plate 57, and this keeps close to it and holds up the paper to theknife; the strip'then advances toward a pair of receiving rolls 60 and 61, the former of which is mountedl in a horizontal position in a bracket frame 62 secured to the main frame 1. These rolls 60 and 61 are driven continuously when the machine is in operation. For this purpose, lthe main shaft 2 is provided` at the right* of the machine, with a belt wheel 63 over which runs a belt' 64, and the upper end of this belt runs over a `small belt pulley 65 which is rigid on the shaft of the roll 60, as indicated in Fig. 1. The roll 61 is not driven and it is not mounted .directly in the frame 62; it is supported on arms 66 which are Jivotally rame 62, and is pressed against the face of the roll 60 by means of a helical s ring-68 vmounted as shown in Fig. 1. Just yond these rollers 60 and 61 I provide a feed drum 69. The construction of this feed drum is as follows: I- provide a finger drum 70 which `ger shafts are provided with rigid fingers which are bifurcated, and each of these finger shaftsis provided with a short arm' 75, as indicated most clearly in Figs. 7 and 8. Each of these short arms is provided with a roller, 76 and these rollers run in cam slots 77 formed in two cains 78 whichare disposed one near each end of the drumf Each of these cams 7 8consist"s of a heart or Imain plate 79 and a' rim 80, the said heart and rim being connected by vconnecting plates 81 and 82, as shown. The connecting plate 82 is extended downwardly below the rim 80, as indicated in Fig. 8, and is formed into a slotted head 83, throu h the slot of which passes an adjusting bo t 84 which is mounted in the frame 62. By means' of these adjusting bolts 84 and the slot heads .83, the exact position of the cams 78 may be nicely adjusted. 0n the upper'sides of the fin ers 74 on the left side of the drum, as in icated in Fig. 6, nibs 85 are provided, which project upwardly, and these nibs operate as stops to hold the under-strips in po-v sition when they are fed to the fin ers from the rolls 60 and 61. I provide strip holders 86 which are pivotally. mounted on the fin ger shafts 73,V and these strip holders have tongues 87 which ro'ect out over the bifurcated fingers; an t ey are also rovided with tails 88 which extend rearwar 1y in an inclined position toward the interior of the drum. (,)n` the nger shafts 7 3 coil springs 89 are provided, which thrust against the tails 88, and in this way the tongues 87 are sprinv pressed toward the iingers.

Re erring especially to Fig. 7, the drum 70 is rotatably mounted on a fixed drum shaft 90, and one end of this shaft is loosely Y mounted in the heart 79 of the cam 78 which is disposed at the right of the machine. It is also loosely mounted in the aforesaid bracket frame 62, andprojects beyond this bracket frame to receive an adjusting arm 91 which is rigidly attached toit. This adjustin .arm 91 extends downwardly, and is provi ed at its lower end with a slotted head 92 through the slot of which an adjusting bolt 93 passes, the said bolt being seated in the side of the bracket frame 62. This adjusting arm 91 is provided for the pur ose of adjust-in the position of a tail bloc( 94 which is rigidly attached to the shaft 90 near the middle of the drum, and in alinement with the tails of the strip holders. As indicated most clearly in Fig. 6, this block has the form of a quadrant, presenting a` cireumferentially disposed face 95 on its under side. The arrangement is such that Vas the fingers descend at the right of the idrum, as indicated in Fig. 6, the tails slide upon this face 95 and rotate the strip holders on the finger shafts. This arrangement the under-strips one by one as they come from the rolls 60 and 61. In order to facilitate this operation, the frame 62 is provided with a plurality of arc-shaped guide bars 96 which extend upwardly over the forward side of the drum; These bars aie attached at their forward ends to the frame 62, and just to therear of the rolls 60 and 61 they are otf. set so as to present horizontal extensions 97, as indicated in Fig. 6. These horizontal ex. tensions 97 form a. shelf which receives the under-strips as they come from the rolls 60 and 61. It should be understood that the is adopted so as to enable the fingers to check fingers-to pass up between them,as indicated inF ig. G. In this way each strip is picked up by a finger, and immediately after it touches the finger the tail of the strip holder carried by that finger, leaves the tail block 94, and its spring then enables it to clamp the strip and hold it in position. My reason for providing two lcams for operating the finger shafts Vinstead of one,is simply one of convenience of'desigrn'as it is found that with one cam only the rollers 76 carried by the arms become too `crowded to operate efficiently. v

An inspection of Fig. 14 will show that the over-strips are punchedby the dies at points equidistant. When these strips are cut off in the finished filler, they' are cut at the points indicated by the dotted lines 98. In this way short stub ends are leftat the 'sides of the liller, which come against the sides of the packing case. It will be clearly seen, then, thatthe punch openings formed in the over-strips which are to come at the ends of the strips, must be closertogether. 0n this account it is necessary to make specialprovision for this in the construction of the drum. The special provision referred to is indicated in Fig. 17. The special arrangement consists in forming the drum so'that at diametrically opposite points, the adjacent iingers Vare placed closer together, and in this connection, it should be understood that with one complete rotation of the drum, sufficient under-strips will be fed to the over-strips to form two complete fillers. It is found that with the finger shafts 73 too close together itis not possible to provide for the operationv '40 of the stripholders, because their tails will obstruct each other. `For this purpose, I provide special strip holders 100 which are mounted on the nger shafts disposed rearwardly with respect to the direction'of retation. These strip holders are formed without tails, but their hub's 101 are prpvided with pins 102' which-areengaged by.coil springs 103' which tend to hold the tongues 104 down against the forward faces o f the fingers. These tongues 104 areattached by' chains 105 to the fingers next in advance, so that thev finger nextin advance holds the fingers 104 in the open position toireceive the strip. In other words, at two points on the.

drums,`it is necessary' to control the' stri holders from the lingers next in advance. t will of course be understood that asthe finger having the tongue 104 rotates upwardly,`

itwill eventually push the tongue 104 upwardly so as to relieve .the tension in lthey .chain 105', and allow the spring 103 to hold the tongue against the face of its corresponding finger. It should be understood that the over-strips indicated'in 14,` as vtheyl pass through. the :forward punches', are

,punched as indicated; that is,'jtl1eya1v'eV 'whichrest upon the plate 115, an

through the vbase'}plat.e'115 alug 125 is provided asainst .scones formed on their lower edgeslwith upwardlyv extending slots 106, and beyond the ends of these slots eyes 107 are formed in alinement A therewith. In this way a bridge 108 of the material of which the strip is formed, is

porduced between the slot and the eye. Thevv under-strips are punched by the dies'so las to -form slots-109 extending downwardly from their upper edges. The lower portions of these slots have lateral offsets l110. At

these offsets 110 the edges of the slots 109 are 4formed with laterally projecting teeth 111,V

there `being one tooth in each slot. These teeth jhave lnclined `upper edges 112 and abrupt lower edges. From this arrangelment, it should be understood that ifthe 111 can be made to engage the eyes 107. In Y this way the under-strips can be interlocked with the over-strips simply by forcing them together .assuggested Referring now to Fig. 1, the dotted outline indicates the continuous over-strips 113 A V as they pass `toward the -upper side of theY drum. Before reaching the drum these strips are guided into proper positions by means of a multiple guide 114. The construction of lthis guide 1s most clearly shown in Fig.

13. It comprises a transverse base plate 115 Y' supportedin the bracket frame 62. Onthe' upper side of this plate 115 a plurality of guide lplates 1164 are provided, which are4 fixed in position. Opposite to these plates 116v similar plates 117 are provided, which are, h wever, movable toward the fixed plates. The forward ends of these plates 116 and 117 are provided with outwardly diverging v flanges 118,'so that enlar ed receivin mouths 119 are formed at theA orward en s of the guides which assist in directing thestripsthrough the guide spacesbetween the plates. The movable guide plates 117 are formed at their lower edges'with` horizontal iian es 120-V y theseV fianges are formed each with. a slot 121 recelvmg a guide screw 122 which is fixed in the base plate.` These guide screws are d isposed near the guides-119. At the opposite -lslde ofthefbase plate, that is,..at the' rear ed e, a plurahjty of springs 123 are provi ed, which are disposed between the guides.

Each springis held in position bya stud l124 which projects 4laterally from the side of the Y movab e guide plate. Allof these sprin press their corresponding. movable gui eplates toward the fixed gu1deplates, so that'V a slight frictional'pr'essure-is exerted uponf the sides of vthe over-strips'as'they pass guides. At the rightof .the

whc

the right-hand spring the them downwardly into perfect engagement aso,ios

over-strips 113pas`s over thef drum the. in-

gers which carry the under-strips present them in succession to the slots 106, and as this beater is clearly shown in 6. .In

'the upper portion of the drum me 62 which extends upwardly for this purpose, a transverse rock shaft 127 is mounted, and this rock shaft is provided with a rigid arm 128. This arm is connected by aV link 129 with a crank 130. This crank is ri 'd with a gear wheel 131 and this gear w eel is in turn driven by a pinion 132 which is rigidly attached to the shaft of the roller 60 referred to above. Rigid with the rock shaft 127 there is provided ahorizontal arm 133, on

the end of which a stem l134 ispivotally hung. The lower end of this stem 134 car# ries a stamper or beater plate 135. In order to give this beater plate a parallel movement, the lower end of the stem 134l is connected by 'a link 136 with the frame 62. From this arrangement, it should be understoodl that as the rock shaft 127 is rocked by the crank 130, the beater plate 135 will reciprocate up and" down so as to strike the upper edges of the over-strips' 113 and force with the under-strips.

. As indicated most clearly in Fig. 6, the

, bars 96 referred to above have horizontal extensions 137 which operate as guides for the filler web. In this connection, it should be understood'that the liller is formed in a continuous band or web. This filler band is cut by means of a multiple knife 138 which operates at theproper moments to cut the over-strips midway between the adjacently placed under-strips.

The mechanism for mounting and operating this knife will now ser so as to form arms 143, the purpose of which will appear more fully hereinafter. Slidably mounted on the side bars or guide bars 140 there is providedfamovmg cross head 144. This cross head consists simply of al horizontal elongated plate which vis enlarged at its ends so as to receive ide openings for the bars 140. To ythe en s of this cross' head 144 links 145 are pivotall attached, and these links` extend downwar yso as to attach to 'rocker arms 146, as indicated in Fig. 6., These'rocker arms 146 are rigidlyattached to a rock shaft 147 mounted in the lower part ofthe rame below the knife.

Referrin now to Fig. 1, the means for actuating t e rock shaft 147 will be described: This com rises a rigid rocker arm 148 which is carrie by the rock shaft`147, and this 'rocker arm 148 is connected by a link 149 with an olfsetcrank 150 which is formed upon the outerside of a ear wheel 151. This gear wheel is mounte on the side of the frame above the belt wheel 63, and is rotated by a gear wheel 152 which is rigid on the shaft 6. These gears 151 and 152 are elliptical gears so as to give a quick movement of the cross head 144 at the time that it descends toward the fillerv web.' At the timethat the cross head 144 has descended so as to cut the filler web, the knife frame' 139 is rocked forwardly so that the knife advances with the continuous movement 'of the filler web. For the pur ose of rocking the knife frame as sug este, I provide an offset bar 153, which is c early shown in Figs. 1 and 2. This bar is pivota'lly attached at its rear end to lixed clips 1.54 on the upper side of the fixed cross head 142, as indicated most clearly n Fig. 4. This bar 153 is given a reciprocatixg movement by-means 0f a mutilated pinion 155 which drives a double rack 155l on the end of the bar.

Referring to Fig.- 5, it will be seen that the shaft 156 is driven from the shaft 6 by means of gear wheels 157 and 158 which mesh t0 ether as shown. This driving means is 'also i lustrated in Fig. 2.

Returning to the description of the knifeo erating mechanism, and referring especially to Figs. 9 and 10, on the face ofthe cross head 144 knife bars 159 and 160 are ico slidably mounted in suitable guides 161. f

The knife bar -160 is provided on its u per edge with lugs 162, and between these u s there is received a projecting toe 163l whic is rigidly carried by a rocking pin 164. This rocking in is rotatably mounted in a beari On the knife bar 159 a plurality of bladesvor cutters 172 are provided. These blades are disposed an equal distance a art and cooperate with similar-blades 1 3 which are attached to the knife bar 160. From this arrangement, it will be understood that the spring tension acting upon the levers 170 tends -to move the toes 163 and 167v outwardly; that is, awa from each other.l and hence the springs 1 1 operate tohold the :blades172 and 173 in their closed position;

' tached by means-of a suitable bracket 176.

This dog has an upwardly projecting tail 177 to which' aV small coiled spring 178 is attached, the forward end of said spring being attached to a fixed clip 179 attached to the lug 174, as shown. From this arrangement, it should be understood that when the#l knife bar 160 is moved toward the left, and the knife bar 159 towardv the right, the spring 178 will operate to pull the dog 175 down into a horizontal position, so that its end engages with the abrupt shoulder of the lug 174, in this way operating'to hold the knife blades apart in the manner indicated in Fig. 9 in dotted lines.

From the 'dog 175 af stem 180 extends upwardly, and this stem is slidably mounted through a guide plate 181 fixed on the cross head 142. 'It should, be understood that this stem slides freely through the guide plate 181 in an upward direction, but on its upper' end lwhich projects beyond the plate, stops or check nuts 182 are placed, which limit the downward movement of the stem. By this means the dog 175 is pulled out of engagement with the lug 174 when the knife has reached the limit of its downward movement. The springs 17.1 then operateto bring the blades 172 `and 173 together so as to cut all of the over-'strips constitutingthe filler web. In this connection, it should be' understood that the blades are disposed at a proper distance apart to receive the over-strips respectively.

In order to set the knife bars 159 and 160 apart sothat the device may be sprung by pulling out the dog 175, I provide, .on the under side of the cross head-'142, downwardly projecting brackets '183. These brackets are V-shaped, `and the lower ends are disposed in the path ofthe levers 170 as they move upwar ly. From this arrangement, it will be 'understoodthat as the cross head 144 moves upwardly, at the end of the upward movement the levers 170 are detained by the brackets1183 so as to rocky the toes 163 and 167. This separates the blades and enables the dog 175 to drop down and-press' the knife bars apart, as will bereadily understood.

In the operation of the knife, it should be understood that when the knife has de scended and during the time that it is being applied to the filler web to cut it, the. knlfe frame is being rocked forwardly with the advancing movement of the Iiller'web. In this way the knife makes a clean cut through the over-strips.

In order to guide the filler web andthe fillers as they are formed from the web, I

this way it projects under the knife and is.-

freely movable; that is, it is depressilole. A

` spring 187 is provided, which is attached to fixed arms 188 on the bars 184, and which 'i tend to hold the bars in a horizont-a1 osition. These bars are pushed downwardlljT bythe filler web when the filler 'web is being cutoff. A

trated in Fig. 7, the means for driving the drum will now be described: For this purrotatablyv mounted in the adjacent bracket 62. Beyond this point the shaft 189 1s provided with a rigid sprocket wheel 190 which i's-driven by means of a chain 191. This chain 191 passes around a s rocket wheel 192 carried by the shaft 6, as indicated most clearly in Figs. 2 and 3.

In order tomodify the operation of the punch 17 so as to make the punch openings come closer together at the points Which-will be the ends of the cut off over-strips, I provide an arrangement illustrated in Figs. 5

and 16. For this purpose, al number of the ,teeth of the main gear wheel 5 are stripped I.

Referring again to the finger drum illus- 4 v80.3 pose, the left-hand head is lprovided With a tubular sleeve or shaft 189,- and this shaft 1sv atv off so as to leave a blank spotor face course, the feeding movement of the stock passingbetweenthe rolls 7 and 8, will cease, and the result will-be that a smaller movement will occur at this time than at'other times. The consequence of this is-'that the punch marks will come closer .together at these points. In order to continuey the rotation of the regular feeding movement after From this arrangement,' the ltrans-l this has occurred, the periphery ofthe pinion 4 is provided with a giant tooth 194 which projects v`outwardly therefrom as shown, and this tooth is adapted. to engage with `a similar tooth 195 which is provided adjacent to the blank face- 193 on the large gear., 'This' arrangement permits the pinion y to make substantially a half revolution atr this time without affecting the gear wheel 5; but after this half revolution is complete,

the giant tooth 194 strikes the tooth 195 and advances the main gear, so that its teeth mesh again with those of the pinion in the normal regular way. v

.The mode of operation of the complete machine will be briefly described: The lstock which is to form the overstri s is ,fed between thel rollers 7 andl 8. Thisstock firstpasses between thepunch 17 and the die 14. The knives 9 on the rollers and cut the stock into continuous bands or strips. As

the stock advances under the punch 17, the .d

, this way the punch passes through the stock and does not tear it. The continuous rotation of the rollers 7 and 8 continues to draw in the stock, and when the punch 17 is out of engagement with its die, the stock advances over the die without being punched. From this arrangement, the punch operates to produce equidistant punch openings in the stock. When the punched stock is cnt into st rips, the strips present the ap earance indlcated in'F ig. 14. It.will be o served that the knives cnt the strips so that the slots 106 are formed at one edge of the strips. These strips then pass toward the rear of the ma# chine, as indicated by the dotted lines in Fig. 1, and pass through the guide 114 and over 'the finger drum 69. As they pass over the finger drum the drum fingers which carry up the under strips, insert the under strips in the slots 106, and the beater 126 operates to force theover-stri s downwardly so that they interlock with t e under-strips by means of the teeth 111 which en ge 1n the eyes 107. From this point the we which is to be cut oif into lengths to form the illers, advances toa point under the knife 138, and the knife operates to cut the over-stri s of the tllersat the proper points. It shou d be understood that the kmfe advances with the filler web .at the .moment that it is cutting the same, from which arrangement it follows that'the knife does not bend or deform the filler. For this purpose, the knife is mounted on the rockin knife frame 139, and it will be understoo that the knife is inanelevated 4position on the return move; ment ofthe frame. On the movement of the frame 139 which' is in the direction in which the web is advancing, theknife descends and cuts the filler at the proper point.' The stock vland this punch 32 advances with the coming from the rolls when the punch is 0p'- which is'to form the under-stripsis fed between the rollers 20 Vand 20* and under' the punch 32. The individual punches are disposed the same distance apart as the slots 106,

erating. 0n its return movement the'punch is open, so that it permitsthe stock to advance under it. 0n each downward stroke unch bar cuts off a strip up to the knife by the plate 57 in the s ace `before the rollers 60 andl. vThesero ers advance the strip onto the' shelfformed at 'the point 97, from which oint the strips are taken by the fingers 74. hese fingers move 'upwardly with thegdrum and present the Vmeans positions of said fingers, cams coperating c with said levers, strip holders cooperatlng with said fingers to ld transverse strips thereupon and spring-pressed toward engagement with said fingers, and a fixed member adapted to be engaged by said strip holders to hold the same away from said fnfrers. 2.
